.a licmtn-aieuanuar 18,1915. sumrxaasez To all whom it may concern Be it known thatl, I'IARRYQEHLIG, a' citi- ,zen of the United States, and a residentof Pearl River, county1of Rock1and,and State of New York, have invented certain new and useful Improvements in (hunter-Op crating Attachments, of which the following is a specification. 1

The purpose .of the. present-invention is to provide a simple and effective attachment for paper handling machinery for op crating the .ordinar counter 'to cause the counter to accurate y register the number of articles passed through and operated upon 'by the machine. {In producingthe mechanism for this purpose I have devised a counter operating attachment which 1s operated by a part of the machine. to which .it is applied .-.and automatically controlled by a detecting" device whichindicates the presence or absence-of the article being operated upon, an'dby such detection determines whether the counter shalloperate.

-Whi1e my invention may be' applied to any machine-arranged to operate upon the products'passed through it, I- have chosen for the purpose of illustration, the application of my invention to a paper folding machinein which an ordinary counting device is arranged .to be actuated by the paper folding knife. An arm connected with the operatlng device of the counter is held normally disengaged from a part' carried by the folding knife and is intermittentlythrown into operative engagement with said part by the operating attachment; a spring actuated member is connected with said arm and held against action by its engagement with the folding knife so that when the knifemoves in its folding operation the counter operating arm is pulled over into the path .of the operating part c upon the knife to causethe operation of "the counter; a sheet detecting member I presented abovethe path of sheets is also connected with said spring actuated member so as, to be lowered into engagement withv a sheet at each operation of the knife, said detecting member having a lost motion connectionwith said spring actuated member so as to permit the detector to stop when it engages a sheet and allowthe continued movement of the spring actuated member,

which movement throws the counter arm into the path of the operating part of the knife and-slightly raises the detector from its engagement with the sheet. A stop arm carried by the detector member rests beneath the spring actuated member when the detector moves beyond its normal position in the absence of a sheet, thereby arresting the spring actuated member in poings and afterward point out the novelty more particularly in the annexed claims.

In said drawings,'- Figure 1 is a detail, transverse, sectional {elevation of a paper folding machine, showing my' improved counter operating attachment applied thereto. Fig. 2 is aplan view of the same, Fig.

3 is a side view of'the same.- Fig.4; is a view similar to Fig. 1, showingthe essential parts of the mechanism in shifted positiQn.

1" is part of the frame of an ordinary folding machine, 2-2 are folding rollers and 3 is the folding knife operated in the usuat-manner;

5 is a bracket secured upon the frame 1 and supporting a counter6 of any ordinary construct on. In the particular counter' shownan operating lever 7 projects from one end.-, 'The operation of the counter is by moving; the lever 7 downwardly 'and back one stroke;

Pivoted at 10 tothe, outer end-of the counter operating lever 7 is a de, ending actuating farm 11 having inward y pre sented hook 12 formed onits lower end. This hook .arm or counter-actuating member l'lis normally presented to oneside of a finger 15, secured at 16 to one end of the folding knife 3, as shown best in Fig. 1 of the drawings. In the operation of the device the hook arm 11 is drawn toward the finger 15 to present the hook 12 beneath finger 1.5 as the knife 3 moves downwardly in the folding operation.

p '20 is an upright bracket .securedat 21' to one of the cross bars 22 of the folding machine at a point preferably adjacent to the longitudinal center of the machine. otallv' mounted at 25 upon the bracket 20 is a-bell crank arm 26 engaged by a spring Piv- 27 which is coiled around the pivot 25 and has one end secured to the bracket at 28 and the other endengaged with one arm of the bell crank 26 to give'the bell crank 26 a spring tendency to rotate on its pivot to the right, in Fig. 1. Theupper arm 26 of hell crank 26 has pivoted toit at 30 a pitman 31 which is pivoted at its outer end 32 to the hook arm 11, so that all movements of the bell crank 26 are transmitted to the hook arm 11. Secured to the horizontal arm 26 of bell crank 26 is an upwardly projecting hook shaped finger 35 whoseupper. hook end rests upon the upper edge of the folding knife 3 rock arm 47 carrying at its ends a pin 48 which engages the slot 49 of the link 50 pivoted at 52 to the arm 26? of the bell crank 26. The detecting finger 45 also carries an upwardly presented stop arm 55 which under certain circumstances is adapted to rest beneath the shoulder 26 of the arm 26 to limit the movement of bell crank 26 an parts connected therewith. Th6 operation of. the device will be understood from the following explanation: A sheet fed into the folding machine passes in position above the folding rollers 2 and is supported by the ordinary bars and slats while it is registered, preparatory to the folding operation. the paper rests above the bars indicated at 1 in Fig. 1, and the counter operating attachment is in the position shown in this figure at the start of the folding operation.

As the folding knife 3 moves downwardly toward the paper, the sheet detecting finger 45 will be lowered Withthe other parts until the blade 46 rests upon the sheet, which will arrest the movement of the detector 45 and stop arm 55. The sheet being in position, the blade continues to move downwardly into engagement with the sheet and its continued movement permits the continued movement of the bell crank 26 which moves the hook arm 11 over to the right until the hook 12 is in the path of the linger 15, so that the completion of the downward stroke of the knife will register one count In this final move-.

In the machine shown arm 55 to slightly raise the detector from" its engagement with the sheet and free the sheet as it is struck through the folding rollers by the knife. This operation takes lace every time a sheet is folded in the ma chine. If a sheet is missed, the detector arm 45 moving down detects the absence of the sheet and by its extreme downward motion places the stop arm .55 beneath the shoulder 26 which limits the movement of hell crank 26, so that the hook arm 11 is notpulled inwardly far enough to engage the finger 15 of the knife. In this operation with a sheet missing, the folding knife goes through its regular operatiombut the counter is not operated. With this simple and effective .mechanism the final amount registered by My improved counter operating. mechanism has been designed particularly as an attachment for paper handling machinery, but I would have it understood that I do not limit my invention to its particular application since it can readily be applied, without essential changes, to any machine through which articles in course of manufacture or treatment are passed and are operated upon'by the machine for any purpose.
